ABSTRACTResistant Gram-negative bacteria are increasing central-line-associated bloodstream infection threats. To better combat this, chlorhexidine (CHX) was added to minocycline-rifampin (M/R) catheters. Thein vitroantimicrobial activity of CHX-M/R catheters against multidrug resistant, Gram-negativeAcinetobacter baumannii,Enterobacter cloacae,Escherichia coli,Klebsiella pneumoniae,Pseudomonas aeruginosa, andStenotrophomonas maltophiliawas tested. M/R and CHX-silver sulfadiazine (CHX/SS) catheters were used as comparators. The novel CHX-M/R catheters were significantly more effective (P< 0.0001) than CHX/SS or M/R catheters in preventing biofilm colonization and showed better antimicrobial durability.
